I'm trying something new as a backdrop for our card game. We have a cat as a "suit icon" that sits in the upper left corner. We want to put a "foggy" backdrop behind the cat that's reddish. So I took a square, but it behind the cat, made it red, blurred it and got it looking exactly the way I wanted it and then realized that the size of that shape became really large and the blur effect ran into a border area I don't want it to extend into. How can I "clip" the effect so that it only extends so far on the top left of the card border, but extends fully into the center of the card? There is a background image (a starry sky) that marks the limit of the edges of the card.
In the example text, I want the blur to appear on the blue card, but NOT outside it in the white area. I feel I'm overlooking something blatantly obvious.
Small problem. In my actual example, the blur extends WELL beyond the "blue rectangle", but the SELECTABLE area doesn't. So, when I put the new rectangle on top of it, I can no longer select it as it's below the new rectangle and unselectable as a result....
If there are no other objects below, which you don't want clipped, you can drag a selection box around everything. You have to drag it large enough to go around the large blur. Use the status bar to make sure you have 3 objects selected.
Or you can use a key shortcut. Click on the top object, hold Shift and Alt, and click again. That adds the object below the blue rectangle to the selection. If you didn't want to select both, but you only wanted to select the blurred object, do the same thing except don't hold Shift.

You want to use 'Clip' on the Object menu.
Duplicate your blue rectange, and make sure the new copy is on top of the red blurred object.
With the new blue rectangle selected, hold down shift and click the red blurry object to select it too.
Now go to Object / Clip / Set. This will contain the red blur within the boundaries of the blue rectangle.
If you need to change or undo, it's Clip / Release.
Hope that's clear. :)
